TELECOMMUNICATIONS INTERFACE FOR UNIFIED HANDLING OF VARIED ANALOG-DERIVED AND DIGITAL DATA STREAMS |
摘要 |
A low-cost yet high-performance, moderate bandwidth (up to 2 Mbps) global telecommunications interface to new and existing computers allows high-performance, low-cost telecommunications platforms to support global fax, data, voice, and other data streams in an intuitive way. The telecommunications interface provides a very low-cost solution to international connectivity for a broad class of existing computers while providing high-performance wide-area data transfer. Convenient and reliable global communications over the phone line may thus be achieved. From a rudimentary viewpoint, the telecommunications interface provides for an elegant, economical implementation of a fax/data modem. The telecommunications interface provides both a time-division multiplexed interface mode for constant bit rate communications and a packetized interface mode for variable bit rate communications. Multiple streams of digital and/or analog-derived data may be handled simultaneously. DMA and non-DMA interface mode am provided in order to achieve compatibility with a broad range of existing and new computers. |
